CARBURETER.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed April 18, 1905. Serial No. 256,323.

- plosion-engines; and the invention consists 1n the novel constructionof the means employed for controlling the supply of liquid fuel.

B and affording a restricted air-passage D between said conduits.

E is the inlet-pipe for the li uid fuel which enters the restrictedassage and F is a valve controlling the ischarge from the conduit E.

The valve F is (preferably in the form of a conical pin seate in the endof the tube E and extending upward through the bearing in the fitting Cout from the same.

G is a head at the upper end of the valvestem F, which constitutes thearmature of an electromagnet II. This .magnet is mounted above theconduit A, preferably by a bracket I secured thereto, and has apole-piece J projectingfrom the core of the magnet. The end of thispole-piece J is apertured in alinement with the stem F and is threadedto receive the adj ustably-threaded extension pole-piece K. Thisextension-piece K may be raised or lowered in relation to the armature Gby screwing it up or down and may be locked in difierent positions ofadjustment by the lock-nut L. :4

M is a gate-valve for variably restricting the air-passage between theconduit A and the conduit B, which, as shown, comprises two sections aand b, which are oppositely slidable in ways in the fitting C. Thesections are operated by suitable means, such as the rotary cam N, whichis sleeved upon the by a handle Q, which may be connected by anysuitable mechanism (not shown) so as to be under the control of the oerator.

The electromagnet H is inc uded in an electric circuit, which, asindicated diagrammatically in Fig. 1, includes a circuit-closerR,operated by a suitable part of the engine mechanism. The timing of thiscircuit-closer is such that the circuit is closed to energize the'magnet H at the period when an air-suction is created by the piston inthe cylinder and is then drawing the air current through the conduits Aand B. When the magnet is thus energized, the armature G will beattracted by the pole-piece K and will be lifted so as to open theoil-inlet conduit E and permit the oil to be atomized by the air currentpassing through the restriction D. As soon as the electric circuit isbroken the valve F will return to its seat, preventing further inlet ofoil.

By adjusting the screw K the distance between the same and the armatureG may be varied so as to alter the lift of the valve. Thus in additionto its function as apolepiece the screw K operates as a stop controlingthe movement of opening of the valve.

The gate-valve M operates as the throttle and is controlled in the usualway with carbureters for this purpose.

What I claim as my invention is 1. In a carbureter, the'combination withan air-induction conduit, of an oil-inlet convalve, an electromagnet, apole-piece proj ecting therefrom, and a screw constituting an extensionof said pole-piece adjustable to-' ward or from said armature.

In testimony whereof I afiix my signature in presence of two witnesses.
